3D Printing Hearing Aid Phonak

Oct 31, 2019

Phonak, a well-known hearing aid research and development company, has partnered with Materialise to create a new solution for designing and producing hearing aids: Rapid Shell Modeling. Prior to this, the production of hearing aids was a labor-intensive job that could only be done by skilled craftsmen. This work is not only time consuming, but also requires a lot of manual retouching in order to give the user the most comfortable experience.

RSM's new digital process scans the patient's ear canal impressions and implements the hearing aid housing in 3D printing, saving significant time and effort and producing a more comfortable, acoustically sound hearing aid.

This disruptive process has successfully changed the hearing aid industry. About 99% of the world's hearing aids are manufactured in this way, helping more than 10 million hearing-impaired patients.
